According to Warner Bros., the reason for the delay isn’t a business decision, but because the fans wanted it:

Based on hearing fans’ excitement over the latest chronicle in Middle-earth, WBIE will release the action game earlier than originally planned at all participating retailers.

They then went on to explain what you need to know about Shadow or Mordor if you’re unfamiliar:

In the game, players will experience the depth of the Nemesis System, where every enemy is unique, differentiated by their appearance, personality, strengths and weaknesses. These enemies are shaped by their encounters with the player to create personal archenemies who are unique to every gameplay session.

Middle-earth: Shadow of Mordor delivers a vibrant game environment where the player orchestrates their personal plan of vengeance as they bend Mordor to their will. The game begins on the night of Sauron’s return to Mordor, as his Black Captains brutally execute the Rangers of the Black Gate. Players become Talion, a ranger who loses his family and everything he holds dear, only to be returned from death by a mysterious Spirit of vengeance. Based on the player’s actions with thein-gameNemesis System, every enemy encountered is distinct and can evolve to become a personal archenemy through the course of the game. As Talion’s personal vendetta unfolds, players uncover the mystery of the Spirit that compels him, discover the origin of the Rings of Power and confront the ultimate nemesis.
